In order to meet the increasing demand for our products in China and overseas, since January, 2011, Sanchai has been constructing a larger-scale modern manufacture base which covers an area of 300 Mu (about 20 hectares) and a building area of 68,000 square meters in Pulu Industrial Park of Tongliang, Chongqing. The annual production capacity will reach 20,000 to 30,000 high-power engines by the time full production starts. Sanchai will by then become one of the five largest high-power engine manufacturers in China.
